described form in Fig. .6, use a spring L bowed at 40, thence bent at 41 and 42 under the holders 35, 36

in a way similar to 21 and 22 but from there at 43 and 44 bent around in the reverse bends 43 and 44 should not direction. These 7 extend out to the ends of the casing H, but normally should engage holders 35, 36.

In Figs. 8 and 9, I show a casing M which is substantially the same as H, except that the front parts forming the holders 50 and 51 are closer to the back 59 than where a different type of spring is to be used.

This spring 55 is bowed so as to curve under and preferably close to the ends and 54 of holders 50 and 51 thence extends out at 56 and 57 so as to ordinarily rest against the back 59. This construction prevents rattling and the spring is of such length that it can spread when yielding.

In addition, however, in some cases I prefer to use a rubber or cork buffer 58 which as shown has a hollow back but which obv1- ously might be solid.

right angle parallel This elastic check helps to take up the shock as in case of a heavy door. i

In Fig. 9, I show in place of the rubber buffer 58, a compound spring 68 shown as being flat at the back 60 where it rests against the back 59 of casing M and rounded at 61 to fit the bow of 55 and having a double or S shaped middle portion 63.

The purpose of this is the same as that of the rubber bnfier 58.

It is obvious that I might use as an auxiliary resilient check, a piece of rubber, a spring such as shown in Fig. 9, a spiral spring or any other kind of spring in connection with any of the other types of bow springs shown and described or these might be omitted from the type of spring shown in Figs. 8 and 9.

For cheapness and to still further make my device resilient, I prefer touse a substantially one piece sheet metal construction Ihe tail 10 is bent back upon itself at 100 to form the back side 17 while the front side 7 and the ends 8 and 9 including the bent over front holders 12, 12 between which is the front spring opening, are all made of the of metal without solder.

thus adding to the resiliency and avoiding rattling. i

In every case, it is desirable that the spring should be so made with reference to the front spring opening and the front holders and the casing itself, that a spring can be slipped in and out either with or without an auxiliary check such as 58 without destroying or distorting the holder.

right angles from- 6 and thence extendlng at another This I claim:

1. In a buffer for doors, the combination of a sheet metal casing formed of one piece of metal including attaching means, sides and a back from which integral top and bottom ends extend at right angles and are then bent and extend as holders short distances parallel. with the back, whereby a spring opening is left in the front; with a bow spring positioned inside the casing and formed of a strip of spring sheet metal so bent out medially as to project through the spring opening in the front and to then extend under the holders and to then be doubled back so that the ends of the spring engage the back of the casing while the junctions between its bowed parts and its ends engage the tips of the front holders; and an auxiliary resilient check member between the spring and casing.

52. In a buffer for doors, the combination of a sheet metal casing formed of one piece of metal including an attaching tail, sides, and a back from which integral top and bottom ends extend at right angles and are then bent and extend as holders short distances parallel with the back, whereby a spring opening is left in the front; with a bow spring positioned inside the casing and formed of a strip of spring sheet metal so bent out medially as to project through the spring opening in the front and to then extend under the holders and thence back so that the ends of the spring engage the back of the casing while the junctions between its bowed part and its ends engage the tips of the front holders.

3. In a buffer for doors, the combination of a sheet metal casing formed of one piece of metal including an attaching tail, sides, and a back from which integral top and bot tom ends eatendat right angles and are then bent and extend as holders short distances parallel with the back, whereby a spring opening is left in the front; with a bow spring positioned inside the casing and formed of a strip of spring sheet metal so bent out medially as to project through the spring opening in the front and to then extend under the holders and to then be doubled back.

4. In a buffer for doors, the combination of a casing including sides, a back, top and bottom ends and holders parallel with the back, whereby a spring opening is left in the front; with a bow spring positioned inside the casing and formed of a strip of spring sheet metal so bent out medially as to project through the spring opening in the front and to then extend under the holders and to then be doubled back.
